2 Claims. (Cl. 239-505) means, which condensate would then drip over the va-.

porizer cap and jar, making the entire device more difli cult than was desirable while also resulting in aloss of effectiveness.

It is therefore the primary object of the present inven tion to, provide a cap and spout construction for a vapor izer which can effectively direct steam in an optimum manner and wherein all of thecondensateis directed back into the vaporizer, thus extending the period of effective operation of the vaporizer between 15-20% by test.

It is a further object of the invention to provide means for avoiding the dripping of the condensate of a vaporizer onto the jar thereof, thus effectively increasing the safety of operation of the device as well as making the device more appealing to handle, since the condensate is uncomfortable to the touch.

An additional object of the invention is to mold the Fig. is a bottom plan view looking along lines 5-5 in Fig. 2; and

Fig. 6 is a sectional detailed view of a modified form of spout.

With continuing reference to the accompanying drawing wherein like reference numerals designate similar cap and spout out of synthetic plastic materials, such as nylon or the like, which because of its'characteristics re duces the amount of condensate while being extremely It was not possible in the prior type construction to employ thesemateria ls because of their thermal expansion characteristics, while inthe present invention the difiiculties heretofore experienced have been eliminated. c

Still further objects and features of the. present'invention reside in theprovision of a cap and spout construction for a vaporizer that is simple to fabricate, eflicient in use, inexpensive to manufacture, and capable of ,being molded in any suitable color to renderthedevice most attractive in appearance.

'I hese, together with the ancillary objects and features of the invention, which will become apparent as the following description proceeds, are attained by this vaporizer cap and spout, a preferred embodiment being shown in the accompanying drawing by way of example wherein: Fig. 1 is an elevational view ofthe'cap and spout combination for an electrical steam vaporizer, comprising the present invention;

parts throughout the various views, reference numeral 10 generally designates a cap comprising a cover plate 12 having a downwardly depending flange 14 integrally molded with the cover plate, which flangeis of avcylin drical shape. Also integrally molded with the cover plate andfdepending from the cover plate are sockets 16 and. 18 reinforced by any suitable arrangement of .strength-; ening ribs 20lfor reception of electrode terminals which are adapted to extend through apertures 22' and 24 formed in the cover plate 12. r

The covering plate v12 has a raised central portion 26 inwardly of'the periphery ofthe cover plate 12. An H-shaped body 28 extends upwardly from the raised central portion26 and includes side portions 30 and 32 of segment shape, interconnected by a transverse portion 34;

It is noted that the H-shaped body rises a considerable distance above the central-portion 26 and surrounds on three sides the spout head 36 which extends upwardly from the central portion A U-shaped groove 38 separates the spout head and the H-shaped body 28.

The spout head is provided with a downwardly and outwardly extending side 40 provided with a spout orifice I 42, the portion of the side 40 at the bottom of the opening -42 being outwardly deformed as at 44 as seen best in Fig. 2. The top of the spout head 36 slants upwardly and outwardly as at 46 and serves to provide a rest for the upwardly and outwardly extending top wall 48 of spout 50.

. The central portion 26 is provided with a depression as at 52 therein forming an important feature of the invention. A drain hole 54 is formed in the cover plate 12 and is in alignment with the depression 52 and is in wardly spaced from the flange 14 which inturnis inwardly of the periphery of the cover plate 12.

The spout 50 comprising a tapered channel shaped member having tapered side walls 56 .and 58 interconnected by the top wall 48 andthe end wall 60 and the side walls. 56 and 58 have horizontal bottom edges as at 62. A lip 64 may be provided on the side Walls 56 and 58 in the form of the invention as is shown in Figs. 1 and 2' while the form of the invention as is shown'in Fig. 6 an obtuse angle 66 is formed at the junction of the bottom edges 62 of the sidewalls with the adjacent edges of the. side walls.

I The bottom edges 62 of the Side walls 56 and 5s and the horizontal bottom edges 68 of theend wall 60'are flush with each other and seat on the central portion 26 within theU -shaped groove 38 with the lip 64 or theportion 70 of the spout engaging the shoulder 72 serving. as a locking shoulder for retention of the spout Within" the U-shaped groove.

Further, the shoulder 72 is designed to function in conjunction with the depression 52 to direct condensate droplets throughthe drain hole 54 and back into the vaporizer jar which is schematically shown in 74.

In operation, steam from 'the interior of the vaporizer will pass out of the orifice 42 and will be directed by the spout 50 towards the patient. Due to the fact that the spout-is made of a synthetic plastic material such as nylon as is the cap 10 there will be less condensation as compared to the operation of a vaporizer having a metal spout. However, there will be condensation which collecting on the undersurface of the spout will be fed back to the spout" head 36 and will collect in the depres- Patented Mar. 28, 1961 sion 52 from which it will be fed back into the jar through the drain hole 54.

Inasmuch as the spout and the cap are made of the same materials, there will be no undesirable relative expansion of the parts due to heating of the part by steam. Further, the nylon is electrically insulative serving to safe-guard against electrical hazards while being resistant to chemical or thermo deterioration.

The depression 52 serves not only as a collection means for condensate but provides the shoulder 72 whereby the spout 50 can be more securely retained in position.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

1. A steam directing cap and spout combination comprising a cover plate, a cylindrical flange depending from said cover plate inwardly from the periphery thereof, said cover plate having a raised central portion, an H- shaped body extending upwardly from said central portion, and a spout head extending upwardly from said central portion and having three sides thereof surrounded by said H-shaped body with a U-shaped groove between said spout head and said H-shaped body, said spout head having a fourth side provided with a spout orifice, said central portion having a depression therein outwardly of said spout head, said cover plate having a drain hole therethrough in alignment with said depression, said drain hole being inwardly spaced from said flange, a spout comprising a tapered channel member having an end wall, the bottom edge of said end wall and the bottom edge of said channel member seating on said central portion within said groove, said spout being spaced from said cover plate by said central portion whereby condensate droplets will be delivered to said depression so as to be returned through said drain hole, said depression forming a locking shoulder, said spout engaging said locking shoulder for retention in said U- shaped groove.

2. A steam directing cap and spout combination comprising a cover plate, a cylindrical flange depending from said cover plate inwardly from the periphery thereof, said cover plate having a raised'central portion, an H- shaped body extending upwardly from said central por tion, and a spout head extending upwardly from said central portion and having three sides thereof surrounded by said H-shaped body with a U-shaped groove between said spout head and said H-shaped body, said spout head having a fourth side provided with a spout orifice, said central portion having a depression therein outwardly of said spout head, said cover plate having a drain hole therethrough in alignment with said depression, said drain hole being inwardly spaced from said flange, a spout comprising a tapered channel member having an end wall, the bottom edge of said end wall and the bottom edge of said channel member seating on said central portion within said groove, said spout being spaced from said cover plate by said central portion whereby condensate droplets will be delivered to said depression so as to be returned through said drain hole, said spout and said cover plate being detachable from each other and being molded of synthetic plastic material, said depression in said central portion forming a locking shoulder, said spout engaging said shoulder.
